go aims. (01142-) This invention relates to spools on whichthread is wound for textile purposes, and to guide supports therefor. Particularly, the invention relates to spools designed to receive silk,

- rayon or other delicate or easily soiled materials.

It is the general object of my invention to provide an improved spool and guide support, so de-' signed that the spool may be readily removed from its supports and that the spool sleeve may be readilyremoved from the spool frame, all without manual contact with the thread wound on the sleeve.

A further object is to provide a guide support having improved means to prevent axial 10st motion of the spool during a winding operation.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawings, in which Fig. 1 is a sectional end elevation of parts of a winding machine embodying my improvements;

Fig. 2 is a partial front view, looking in the direction of the arrow 2 in Fig. 1;

Fig. 3 is a side elevation, partly in section, showing a spool frame and spool sleeve partly separated; I

Fig. 4 is a sectional side elevation of my improved spool;

Fig. 5 is a front view showing the manner of removing the spool from its guide supports;

Fig. 6 is a front view showing the manner of removing the spool frame from'a spool sleeve having thread wound thereon; and

Figs. '7 and 8 are detail sectional views, taken along the lines 1-! and 8-8 in Fig. 1 respectively.

Referring to Fig. l, I have shown portions of a winding machine including a rail H] supporting brackets I! which provide spaced bearings for a winding shaft [2 which drives a plurality of axially-spaced winding rolls l3. The brackets H also uphold a cross bar I5, to which guide supports l6 for the winding spools are secured by clamping bolts I1. I

Each guide support comprises a fixed frame member 20 having a substantially vertical guide groove 2| in one face thereof and a rectangular recess 22 in the opposite face. A block 24 is loosely mounted in the recess 22 but is secured from outward displacement by headed studs 25 fixed in the frame member 20.

Coil springs 26 are interposed between the block 24 and the member 20 and hold the block 24 yieldingly' in the outward-position shown in Figs. 7..and..8.= The springs 26 are seated in aligned recesses 2iv and 23 in theframe member .20 and block 24 respectively. "A guide groove- 29 is provided in the block 24, which groove is alignedawith the, fixed. guide groove 2 I previously .describedm.

. ThespoolS is supported on a shaft 30 (Fig. 4), the ends of which iiare received in the guide grooves 2i, and 29 when-tthespool is'in winding position. A pin 3| in one end of the shaft 30 engages a side wall of the associated guide groove and holds the shaft 30 from rotation.

The spool S further comprises a frame F, and a sleeve V on which the thread T is wound.

The spool frame F is formed with dished sheet metal heads 33 and 34, secured in fixed axial relation by longitudinal connecting members 35, and rotatably mounted on the shaft 30, preferably by anti-friction bearings 36 and 3'! provided with suitable dust. covers 38. The bearings are located on the shaft 30 by collars 39 which prevent relative end movement of the bearings.

The sleeve V may be of any suitable sheet material, such as vulcanized fibre or a synthetic resinous material, and is designed to slip easily over the heads 34 and 33 and to be positioned axially by an end flange 4!] on the head 33.

The frame F is provided with a pair of driving levers 42, pivotally secured at one end in slots in the spool head 34 and having their opposite ends 43 extending through openings 44 (Fig. l) in the disc portion of the head 33.

Expansion springs 45 are interposed between the levers 42 and act to force the levers apart and outward to nesting engagement with associated connecting members 35. Pointed studs 48 are mounted in the levers 42 and extend through openings 49 in the associated members 35. The pointed studs 48, when the levers 42 are released, move outward into holding and driving relation with the sleeve V assembled on the frame F, and prevent either longitudinal or axial displacement thereof.

The spools are mounted between pairs of guide supports l6, and each spool, or the thread T wound thereon, engages one of the driving rolls I3 and is continuously rotated thereby. As the Winding of thread increases in thickness, the

spool moves freely upward, but is guidedv and retained in position by the grooves 2| and 29 in the supports l6.

After the desired amount of thread has been wound on a spool, the spool may be removed as indicated in Fig. 5 by inserting the fingers into the recessed spool heads and lifting the spool S advantages thereof, I do not wish to be limited and spool shaft 30 out of the guide grooves 2| and 29. As this movement is approaching completion, the ends of the shaft 30 engage guard plates 55 (Fig. 1) on the upper ends of the supports l6, so that further movement must be forward as well as upward and the filled spool is thus kept clear of contact with adjacent parts of the machine.

After the spool has been thus removed, the operator grasps the ends of the levers 42 as indicated in Fig. 6 and presses them inward, whereupon the sleeve V and the thread T wound thereon may be deposited on a supporting surface and the spool frame F may be freely removed upward, all withoutv contact with the thread T. This is extremely desirable when handling silk or rayon or similar materials in which the appearance is altered by the slightest contact therewith.

It will be understood that the number of spool frames F need be sufficient only to fill the wind ing machine, while spool sleeves V only need be provided for any required number of thread packages. I

Claims to the novel guide support disclosed in this specification are not presented herewith but form the subject matter of a divisional application Serial No. 338,483, filed by me June 3, 1940.

Having thus described my invention and the to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1. In a winding machine, a spool comprising a spool frame having inwardly recessed heads, a cylindrical yarn-supporting sleeve mounted on said frame, a pair of levers each pivoted at one end in one of said heads, the free ends of said levers extending into openings in the other head for manual release, springs to force said levers apart, and spurs on said levers engaging the inner surface of a sleeve mounted on said frame and preventing axial and angular displacement thereof on said spool frame.

2. In a winding machine, a spool comprising a spool frame having longitudinally spaced heads, axially extending bars connecting said heads and maintaining them in fixed spaced relation, a pair of diametrically opposed levers pivoted in one of said heads and freely movable radially in slots in the other head, spring means to move said levers yieldingly outward and a cylindrical yarnsupporting sleeve axially slidable on said heads and connecting bars, said levers having sleeveengaging and driving elements mounted thereon and certain of said bars having transverse openings through which said elements are projected outward by said spring means to engage said sleeve.
